What is CNC lathe?
A precision CNC lathe is a machine tool used for precise machining of cylindrical or tapered parts. It has a high-precision spindle and guide rail system, as well as advanced cutting and control systems to ensure high-precision machined surfaces and geometries.
Precision CNC lathes use rotary cutting to fix the cutting tool and allow the tool to move along the axial direction of the workpiece, using cutting force to process the workpiece into the required shape and size. It is generally suitable for processing cylindrical or conical surfaces, or for processing high-quality cylindrical or conical parts on various materials, such as shafts, holes, steps, etc.
Precision CNC lathes usually have relatively simple structure consisting of a spindle, a feed box, a slide box, a bed and other parts.
What is a CNC Milling Machine?
A precision CNC milling machine is a machine tool used to process parts of various shapes and sizes. It has a high-precision spindle and tool system, and an advanced computer numerical control (CNC) control system to achieve high-precision machined surfaces and geometries.
Unlike CNC lathes, precision CNC milling machines use rotating milling cutters to clamp the workpiece on the workbench and process it by controlling the axial direction and rotation angle of the cutter. It is usually suitable for processing various shaped surfaces, including planes, inclined surfaces, arc surfaces, etc., or for processing high-quality complex parts on various materials, such as gears, turbines, blades, etc.
The structure of precision CNC milling machines is relatively complex, usually consisting of a spindle, a workbench, a feed system, a control system, etc., and most of them are vertical structures that occupy a large area.
Characteristics of CNC Lathes
Precision CNC lathes often excel at machining shaft-type parts.
Precision CNC lathes have high accurate tolerance up to micron level or even higher, which allows it to process high-precision parts.
In addition, precision CNC lathes are suitable for processing parts of various types of materials, such as steel, aluminum alloys, copper, etc.
The spindle speed of precision CNC lathes is very high, which can complete a large amount of cutting in a short time and improve production efficiency.
Characteristics of Precision CNC Milling Machines
Precision CNC milling machines can control multiple axes at the same time to achieve multi-axis linkage to complete the processing of complex-shaped parts.
The cutting speed of precision CNC milling machines is generally higher than that of CNC lathes, and they can complete large-area cutting faster, which enables them to complete the processing of complex parts in a short time.
During operation, the milling machine will move the workpiece up, down, left, and right in the plane (X-Y), and after reaching the target position, it will mill the workpiece vertically (Z) up and down. Milling machines can perform 2D or 3D diverse processing by changing the shape, rotation mode, angle, etc. of the blade.
Application of Precision CNC Lathes in Industrial Production
CNC lathes are mainly used in industrial production to process cylindrical, conical parts or various rotating parts, such as shafts, holes, steps, sleeves, gears, etc.
Common processing items include internal and external cylindrical processing, drilling, threading, cutting grooves, end face processing, cylindrical turning, center hole drilling, hole turning, reaming, cone turning, forming surface turning, knurling, coiled springs, etc. And some parts that require high-precision outer circle, end face and inner and outer conical surfaces.
Application of Precision CNC Milling Machines in Industrial Production
Common processing projects of precision CNC milling machines in industrial production include plane milling, groove milling, curved surface milling, gear milling, cam milling, turbine milling, blade milling, etc. It can also be used to process parts with complex shapes and structures, such as frames, racks, etc., and can be processed efficiently through multi-axis linkage.
CNC Lathe or CNC milling?
So which one should you choose for processing? Then you have to consider multiple factors such as production cost, production efficiency and quality, and also combine their own advantages, manufacturing requirements for processing workpieces and specific application scenarios to choose between precision CNC lathes or precision CNC milling machines. Sometimes they also need to be used together. .
From the above summary we can see that CNC lathes are best suited for manufacturing cylindrical parts, the cross-section of the part must be circular and the same central axis must run throughout its entire length. Milling machines can also machine cylindrical features, but if the part is purely cylindrical, a CNC lathe is a better and more accurate choice.
If you are processing parts with complex shapes and structures, precision CNC milling machines are the best choice.
